Intravascular ultrasound (IVUS) enables healthcare providers to assess blood vessels from the inside. It uses sound waves to check for narrowing and blockages that can compromise blood flow. IVUS is a minimally invasive procedure involving tiny instruments and sophisticated technology for evaluations that are gentler on your body.

2022年8月13日 · IVUS作为斑块诊断最常用的成像技术，可提供分辨率约为100微米，成像深度约为7毫米的血管横截面结构图像， 但无法显示与斑块易损性相关的微观特征，譬如新生血管、巨噬细胞聚集和薄纤维帽等。 IVUS在经皮冠状动脉介入 ( percutaneous coronary intervention,PCI)手术中可起到重要的辅助决策作用，包括术前评估及术后优化： 1）PCI术前，IVUS主要用于评估斑块性质和特点，制定合适的预处理策略，测量病变长度和参考段血管直径，选择合适的支架直 …

2023年5月22日 · Intravascular ultrasound (IVUS) is an intravascular imaging modality primarily used in interventional cardiology to characterize lesion morphology, quantify plaque burden, guide stent sizing, assess stent expansion, and identify procedural complications.[1]

2024年3月28日 · 血管内超声（intravascular ultrasonography，IVUS）是近年来出现的能够在体评估冠脉斑块的腔内影像学技术，通过在血管内放置超声探头来获得血管壁和周围组织的高分辨率图像。 与传统冠脉造影相比，IVUS能准确判断冠脉狭窄程度和区分斑块类型，在高危斑块的识别、评估以及经皮冠状动脉介入治疗（percutaneous coronary intervention，PCI）治疗策略的制定中提供了无可比拟的优势。

Intravascular ultrasound (IVUS) or intravascular echocardiography is a medical imaging methodology using a specially designed catheter with a miniaturized ultrasound probe attached to the distal end of the catheter.

Intravascular ultrasound allows physicians to see inside the coronary arteries. Longitudinal and cross-sectional images facilitate accurate assessment of plaque morphology, vessel size and lesion length enabling you to deliver precise PCI.

Intravascular ultrasound (IVUS) is a catheter-based coronary imaging technique. It utilises the emission & subsequent detection of reflected high frequency (30–60 MHz) sound waves to create high resolution, cross-sectional images of the coronary artery. IVUS has been the cornerstone of intracoronary imaging for more than two decades.

2018年8月28日 · IVUS images are generated using high-frequency sound waves from a piezoelectric crystal (10 to 40 MHz) to penetrate tissue, reflect off vascular structures and return to the transducer to produce multidimensional images of the vessel. The device is …

2020年11月18日 · An intravascular ultrasound is a minor procedure used to diagnose and treat coronary artery disease. It is a catheter-based procedure that helps your doctor see how much your arteries have narrowed or thickened.

Intravascular ultrasound (IVUS) uses a transducer or probe to generate sound waves and produce images of blood vessels. When used to evaluate the coronary arteries, IVUS can show the entire artery wall and provide important information about the amount and type of plaque buildup, which can help determine if you are at risk for heart attack.
